Local fix

  • Set the following enviornment variable :-
    JPI_PLUGIN2_NO_HEARTBEAT=1
    

Problem summary

  • The reason of the crash is due to the fact that within hearbeat
    timeout value (which is hardcoded as 10 secs) we are not getting
    a hearbeat reply. Due to the above reason its killing the sub
    process and resulting into a crash.
    

Problem conclusion

  • This defect will be fixed in:
    6.0.0 SR10
    6.0.1 SR1
    .
    JVM has been modified so that heartbeat suspend is applied for
    the JVMInstance heartbeat thread similar to the PluginMain's
    one.
    .
    To obtain the fix:
    Install build 20111022 or later
    

Temporary fix
